The NESCAFÉ Alegria A510 is built to make great coffee with minimum fuss and maximum efficiency. For the black coffee options -- Espresso, Lungo or Americano -- just place your cup in the machine and select your option. For the Cappuccino and Latte Macchiato: add fresh milk into your cup, select your choice and watch the NESCAFÉ Alegria A510 get to work while you take five from the desk. Because the NESCAFÉ Alegria A510 warms and froths the milk in your cup without coming in contact with the machine, it requires far less maintenance and cleaning. NESCAFÉ Alegria A510 machines are available with two water tank options depending on how much coffee you plan to consume and where you plan to place the machine: 2.0 litre and 0.8 litre water tank.
